Title: Improvements in or relating to electrical switches
IPC: H01H9/54
Filed: 1919-01-29
Abstract: 142,190. Attwater, T. W. A., and Southern Transport Co. Jan. 29, 1919. Switches; sparking, preventing.-A switch for de-energizing a highly-inductive load, for example a lifting magnet or a magnetic clutch, leaving the magnetic circuit of the load free from residual magnetism, comprises a contactmember which, by continuous movement in one direction, co-operates with fixed contacts to provide a discharge path for the load current by shortcircuiting the inductive load, and an interruption or suspension in the supply to the load, next a reversed connexion of the supply to the load, and a discharge path for the reversed current, and finally an interruption of the supply. In the construction shown in Fig. 1, five similar fixed contact rings B - - F are mounted within an insulating liner A' supported by a housing A and separated from one another by insulating-rings G. The contact rings are engaged by two " brushes " in the form of split rings J, J<1> insulated from one another and mounted on a rod H, so that the brushes may be drawn along the fixed ring contacts. The connexions to the inductive load M and to a resistance R are shown in Fig. 4; the rings B, F are permanently connected together. In positions (1), the load is energized with the resistance R in series; in position (2), the load is short-circuited by the brush J, providing a discharge path for the inductive load; in position (3), the short-circuit is removed and the load again connected to the supply, which now, however, flows through it in the reversed direction; in position (4) the conditions are again as in position (2) and in position (5) the circuit is completely broken. In a modified construction, Fig. 3, the ring B, is divided into four smaller rings B<1> - - B<2>, and the circuit connections are as shown. In this arrangement, there is no resistance in the circuit in the " full on " position, and the load discharges through the resistance instead of through a short circuit.

Abstract: 124,544. Sellers, F., and Daniel, J. W. Feb. 9, 1918. Yarns, beaming; dressing warps; tensioning yarns in warp form.-In a warp beaming, dressing. stashing, or like machine, one or more takeup rolls are mounted in a carriage movable between vertical guides and acted upon by a cord passing over a pulley and connected to a weight to take up the slack warp when the beam is turned back, the weight being normally anchored to the ground by a supplementary cord and weight or spring but being capable of rising upon abnormal tension coming upon the warp. Thus, in a dressing and beaming machine, the warp 3 passes from a ball 4 through guides 1, 2, over and under tension-bars 5, and over a roll 7 and stangs 8, 9 to a final roll 10, whence it passes over a take-up roll 12 in a carriage 13 to a second fixed roll 11, and' through a reed 20 and an expanding raithe 21 to the beam 6, which is driven in the usual manner. The carriage 13 is guided between vertical guides 14, antifriction rollers being employed if desired, and is connected by one or more ropes 15 passing over pulleys 16 to a weight 17, which puts tension on the warp and causes it to be taken up by ascent of the roller 12 when the beam 6 is turned back to find a broken end. The weight 17 is anchored by a rope 18 to a spring or a weight 19, which is raised upon abnormal tension being put on the warp and may actuate a stop-motion or sound a bell. The upper bar of the reed 20, which may be supported by a cord 23, has an attached clamp, in which is secured a stick 25 with a vertical groove for the passage of the warp 3 at the end held by the operative, who is able to feel when the warp clicks or becomes entangled in the ball 4. The carriage may be provided with two take-up rolls acting in conjunction with three fixed rolls on the frame.
